Screen Rant sat down with Josh and talked about his character, changes from the first film, Matt’s relationship with Alejandro, and Josh’s future in the Marvel Cinematic Universe.

SR: What brought you back to this one? And what did you want to explore with your character?

Josh: I don't think I had an intention to explore anything in particular. I think that, Taylor, when he wrote it, Taylor Sheridan, I think he had an idea of a trilogy. Of doing three. And Benicio is always a major draw for me. We've done a lot of movies together. Five so far. And I have a feeling we'll do more. There's something that happens when you have a trust with somebody and it feels less competitive. I don't have that necessarily, maybe because I'm older. Not older than Benny. But we're the same age. When you work with younger people they're all trying to do the best thing and all that. Whereas Benny and I just kind of had an easy volley back and forth. And we can kind of get into the emotion of it quicker. He was a major draw to me. Dariusz Wolski was a major draw to me. Taylor Sheridan, I think is a very, very special guy right now. Pretty brilliant. So yeah, there were a lot of elements. Black label media huge for me.

SR: Was there anything that you brought to the character that wasn't necessarily on the page, this go around?

Josh: Yeah. We talked about it a lot. But I like that there's some time between the end of the first one and the beginning of this one. So, what we talked about is, he was so invincible in the first one. He's so arrogant in the first one. That I wanted to see that start to crack a little bit. So, when you see him, there's a little more weight to him psychically and physically and all that. His eyes are a little swollen, so you can tell he's kind of been through something. And this idea of invincibility is not really working out anymore. So, I always see this movie as the movie of consequence. It's like nothing's quite working out as well as it did before. It's not like that.

SR: Talk to me about the relationship of how Matt might view Alejandro this go around.

Josh: I think he views him the same in the beginning. And the thing is, again, you have this big military or governmental plan. I'd rather call it a governmental plan. And then, this is his guy, this is the guy that he uses. And like Benny and I, we trust each other and all that. We work well together. There's a shorthand and all that. And then there's a humanity that sneaks in there. This relationship with this girl that reminds him of his daughter. Me. I have a relationship with him. So, the government is telling me to do something. And I don't like that. And I start reacting to that. So, I like the fact that something gets broken in this. And then what shows through is the humanity of both these characters, that you didn't necessarily see in the first movie.

Josh Brolin in Sicario: Day of the Soldado

SR: Absolutely. Now I'm switching gears for a second. A lot of our readers are huge fans of you as Thanos and Deadpool. Are there any plans post Avengers 4? Because I know that Marvel's developing The Eternals, which Thanos-

Josh: I didn't know that.

SR: Oh yeah. Thanos is a big part of it.

Josh: Does that mean I’ll be in it?

SR: That’s what I’m hoping.

Josh: That’s good to know. (LAUGHS)

SR: Because Thanos is such an interesting character. Half philosopher, half warrior. And you portray that perfectly.

Josh: Yeah, but you know what, I don't know what the future brings. Who knows? But I love the idea of something finite like this. I've never been involved in sequels. The fact that we've done some of the Avengers 2, sorry, Avengers 4, but Infinity War 2. I’m going back and I'm going to do more. We're going to do some reshoots and all that. So, I'm excited about that. I love the Russo's. I love working on Avengers. I didn't think I was going to. And I actually loved it. I didn't even like it. I loved it. I like playing that character. It's a Brando-esque kind of Apocalypse Now character. And it's fun. But don't know. I don't know what the future holds. I've been surprised my entire career. So, we'll see.
